<p>The present invention relates to an apparatus for measuring a sensor waveform in an automobile and, more specifically, to an apparatus for measuring a sensor waveform in an automobile, capable of directly and accurately comparing and analyzing a normal value and a threshold value of the sensor waveform in an automobile by contrasting and displaying a determined reference sensor waveform after automatically determining which sensor outputs an inputted waveform using a characteristic value of a sensor. To this end, the measuring apparatus for the sensor waveform comprises: a sensor signal input unit (110) consisting of a connection terminal directly connected to a component terminal such as a signal wire or a connector of components in an automobile; a sensor determining unit (120) automatically determining which sensor is measured by the currently inputted waveform using a sensor characteristic value DB (160); a control unit providing waveform analysis information by comparing the sensor waveform and the reference waveform; a display unit (140) outputting the sensor waveform inputted in the sensor signal input unit (110) and the reference waveform extracted by searching from a reference waveform DB (170); a sensor characteristic value DB (160) storing the characteristic value such as a frequency of the sensors installed in an automobile, a peak value, an absolute voltage, a duty, a waveform pattern, or the like; and a reference waveform DB (170) storing the reference waveform of the sensors installed in an automobile as well as the normal value and the threshold value thereof.</p> |
